5 port IMO is the best all around.. 3-port typically will have slightly more bottom end, and they tend to get slightly better fuel mileage then higher port count motors, 7-port is typically the screamer, with the worst fuel mileage.. This is assuming timing is the same on port counts.. But most manufactures change timing from one version of engine to the next to get the most out of each engine.

Anyone know where the cody king or tebo engines are in stock at? Can't find them anywhere.

According to Horizon, who imports the Orion engines, the won't be instock until May for the US market.. A fw guys from Europe have posted pic of their WE engines how ever, so check the European markets, if you just can't wait..

Thanks! I think I'll just go for the King/Tebo kit. If it's good enough for the WC it's good enough for me. :lol:

BTW - Orion's website shows that these are in stock but you can't purchase them on the site. Other Orion products that aren't shipping yet, like their new ESCs, show as "Backorder" so that makes me think that the engines are available now/soon.

Check out Horizon. They are the importers for Orion to the US.. They may be in stock.. I haven't checked in a week or more..

Im looking to make the change to Orion and was checking out the combo's.

Is this the best setup or am i better off gettin the engine seperate with a diff pipe. Thanks!

I'd consider a different pipe, either the 2058 or the 2013. Not seem to tune easier, and both make much better bottom end.. 2057 is a good pipe and makes good power, but it takes alot away from the bottom end.. But in some situtations it is an excellent choice..

Thanks im puttin it in a buggy so a lil away from the bottom wont hurt. Id like to get the 5 port but cant seem to find on anywhere

I am getting the King version as I really appreciate all of the help pitpop.

PS. Have been running a 7 port CRF for some time and have had trouble with the tune from the start and have flamed out many times after a pit stop. Any advise would be helpful.

I know PitPop will give better info, but how close to empty is the tank at the time of refuel? I've seen some engines go from those lean low tank conditions to uber rich and cause problems.. It usually results in a tuning issue, bottom end too rich I think..

can smbody plz help me out and tell me the difference between the team orion engines and the alpha engines (made in taiwan which lutz uses) ..
and also where is team orion engines made ? i was told by a track person dat alpha and team orion alpha engines are same with a few diffrnces?? is it true .. im a newbie so i dnt knw much .. hellp is greatly appreciated ..

This may be it as I have the tendency to load up any time the engine idles for more than just a few seconds. I always blow a bunch of smoke like an old truck upon opening the throttle. Once it clears out I'm fine.

It seems like the line between too rich and too lean is very fine on the low end?

The only similarities between Alpha and Team Orion Alpha are the names, and that they are Nitro Engines.. Not 1 part is interchangable from one to the other. They both perform well in capable hands, but they are not the same.

The Team Orion engines are made at the LM Factory in Italy. The Orion looks to me to have a better fit and finish over all, IE less break-in time, mean your racing sooner. Life on each when tuned and maintained correctly is very similar with each getting 5-6 gallons easily. But, keep in mind many Alpha drivers spend nearly 2 gallons doing break-in while Orion drivers are race tuned at less then 1 gallon. What I am saying is you have potential to get another gallon of FUN from Orion.

If you decide to get an Orion PM me, I'll give you some info on an excellent price for the Discovery engine with 2013 pipe.

Yes it can be, but I haven't noticed that with my orion.. You might also be a bit lean on top. My suggestion is next race day, lean the bottom end and hour or 2, and richen the top and hour or 2, depending on performance of course.. When it is tuned right you will know. Also consider replacing your glow plug.. A weak plug can cause similar tuning headaches.

I am big on changing the plug so I doubt this is it. As for the top end, I get good smoke out of the corners and have temps in the 210 to 230 range so I doubt the top end is lean. The problem arises when I try to lean the bottom end, I sometime get a bog when I try to give it throttle.

If I lean at full operating temp of 200 + I have better luck but find it difficult to keep it in this range while I'm trying to adjust it and end up putting it back on the track in the 170 range.

Since I always preheat to about 150 shouldn't I be able to get it close at this time, or do I have some small leaks that are causing this. I have ordered new seals for the carburetor and am planning on pulling the needles and carb and reinstalling all with grease.

The engine now has 4 gallons through it and still has very good pinch. The tunning issues I am mentioning started during break in after about 1 quart of fuel. I did add booster to the first 1/2 gallon of fuel se there was a lottt of oil present during the first 1/2 gallon.

For what its worth, I started with a # 6 plug and switched to a # 5 after about one quart as I couldn't keep it lit with the # 6.

Thanks for all the help.
